I restored your NVRAM backup to one of my CC2652 coordinators and was able to join a device on my first try, no issues here.

#

The bug I mentioned yesterday would generate a bunch of warnings during the network backup, which I did not see happen with your NVRAM backup. I don't think your problem is related to it.

#

Can you run an energy scan https://github.com/zigpy/zigpy-znp/blob/dev/TOOLS.md#energy-scan ? Maybe it's something RF related. I temporarily moved by CC2652R next to a USB 3 hub the other day and it rendered it completely useless, no data was being sent or received from sensors and bulbs in the same room with a clear line of sight to the coordinator.

#

I will try that

#

I was able to get them paired again by adding devices through the router instead of the coordinator, the router is further away so that's a little strange

#

How do you usually add devices?

iron plume Oct 5, 2021, 10:15 PM

#

I just click the add device button on Zha usually

prisma flower Oct 5, 2021, 10:41 PM

#

That permits joins through every router on the network in addition to the coordinator, which is usually what you want to happen

#

yeah, I think there is something bizarre happening where that isn't being triggered for whatever reason

#

Going to do the energy scan, if I find a better channel. I know I have to reform a network if that is the case...does that mean manually re-pairing every zigbee device?

#

So it looks like 20 and 25 are good. Not sure what current channel is... (15 is default?)

prisma flower Oct 5, 2021, 11:41 PM

#

Your network for some reason is on 11

#

What does the energy scan graph look like after five scans?

#

You may not have to change channels

#

Do you have a strong 2.4GHz WiFi network on channel 1 nearby?

iron plume Oct 5, 2021, 11:48 PM

#

yes

prisma flower Oct 5, 2021, 11:48 PM

#

If it's yours, try moving it to 6 or 11. WiFi networks handle channel changes a whole lot better than Zigbee (which for the most part doesn't).

#

it is my neighbors, but they're pretty chill so I will see if I can get them to move it. Probably took 1 (moved in a week or two ago) because mine are on 6

#

Do you have debug logging enabled for ZHA?

#

If it's been running for a while, search for Request failed. Do you ever see MAC_CHANNEL_ACCESS_FAILURE as a failure reason?

iron plume Oct 6, 2021, 12:04 AM

#

Nope, didn't enable that but I can

#

I will have to get back to you on that one

prisma flower Oct 6, 2021, 12:05 AM

#

That's what Z-Stack responds with when you try sending something and the channel is too congested

#

I'd let it run overnight and then try joining a device or something tomorrow, that should provide more context

iron plume Oct 6, 2021, 12:09 AM

#

I believe that's likely the case. Thinking back, my neighbors moved in recently and that could be the change- i hadn't put it together but that's why it's been wonky the last week or so

prisma flower Oct 6, 2021, 12:12 AM

#

If your network is mostly routers, changing the Zigbee channel might work if you power cycle them but having nice neighbors is a lot easier

iron plume Oct 7, 2021, 7:14 PM

#

Here are some logs from recent: https://pastebin.com/d25ESZ0M

#

Verified that neighbors are not on channel 1, no significant wifi rssi anywhere in that range.

#

Any instances of MAC_CHANNEL_ACCESS_FAILURE in your log?
